CONTROLLED ROCKET ENGINE Russian patent published in 2001 - IPC

Abstract RU 2171389 C2

FIELD: rocketry. SUBSTANCE: proposed invention can be used in designing of solid-propellant rocket engine with wide range thrust control in flight. Rocket engine has housing 1, charge 2, nozzle 9 and hydraulic unit consisting of cup 3 pointed inwards the space of housing 1, piston 4 installed in cup 3 for longitudinal travel, liquid cooling agent 6 located in under-piston space 5 of cup 3. Under-piston space 5 of cup 3 is coupled with nozzle unit 7 pointed into space of housing 1. Piston 4 is of differential (stepped) make. Adjustable throttle 8 is installed between under-piston space 5 and nozzle unit 7. EFFECT: simplifies design, reduced mass, increased summary operation time on specific kind of fuel at preset overall dimensions of engine, reduced transient process time. 2 cl, 3 dwg
